algorithm Bucket Sort Bucket Sort Basic Information


Bucket Sort is a sorting algorithm in which elements of input array are distributed in buckets. After distributing all the elements, buckets are sorted individually by another sorting algorithm. Sometimes it is also sorted by recursive method.

Pseudo code for Bucket Sort

  1. Let n be the length of the input list L;
  2. For each element i from L
  3. If B[i] is not empty
  4. Put A[i] into B[i];
  5. Else B[i] := A[i]
  6. return Concat B[i .. n] into one sorted list;
